Coccomyxa sp. C-169 ARID Family

Description

Kortschak et al. 2000: Members of the recently discovered ARID (AT-rich interaction domain) family of DNA-binding proteins are found in fungi and invertebrate and vertebrate metazoans. ARID-encoding genes are involved in a variety of biological processes including embryonic development, cell lineage gene regulation and cell cycle control. Although the specific roles of this domain and of ARID-containing proteins in transcriptional regulation are yet to be elucidated, they include both positive and negative transcriptional regulation and a likely involvement in the modification of chromatin structure.

Patsialou et al. 2005: The ARID (A-T Rich Interaction Domain) is a helix-turn-helix motif-based DNA-binding domain, conserved in all eukaryotes and diagnostic of a family that includes 15 distinct human proteins with important roles in development, tissue-specific gene expression and proliferation control. Most ARID family members have not been characterized with respect to their DNA-binding behavior, but it is already apparent that not all ARIDs conform to the pattern of binding AT-rich sequences
